Be it known that I, DURBIN VAN LAW, a'

iornia, have invented certainnew and useful Improvements inVheel-Mountings; and l do hereby declare the following to be afulh'clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. l v

This invention relates to wheel mountings and particularly to, mountingsfor the rear wheels ot two wheel vehicles such as bicycles and motorcycles. y

0n the standard makes of two wheel vehicles the rear wheel is mountedupon a stationaryv axle with internal hearings working inside therevolving hub of the rear wheel, In such structures, the rear wheel canonly be removed by 4disconnecting the ends of the axle from the forks orframe supports. rlhis operation necessitates the loosening ot the nut-son the threaded ends of the axle, removingr the wheel alinement screwsand rings, .disjointing the chain, and disconnecting the brake band andconnecting rod. Such removal ofthe rear wheel is an absolute necessitywhen a certain class of tire re- !pairs and removal and substitution oftires have to be made. Under present conditions the operation is atedious one involving considerable time, and disagreeable work whenperformed on the road.

It is therefore the object of the present invention to facilitate theremoval oif the rear or driving 'wheel of any two wheel vehicle. or ofany vehi cle where the power is applied to a single wheel having aforked support for the axle. whereby quick tire repairs or changes, andalso/such other repairs as can be best accomplished with. the wheeldemounted, are rendered possible.

A further object of the invention resides in a wheel mounting of thecharacter referred to so constructed that the removal of the wheel fromthe vehicle can he/eccomplished without disconnecting the drive Chain orbrake' and without molesting the wheel alinement screws and rings.

lith the above and other objects in view the invention consists in thedetails of construction and. in the arrangement and combination of partsto he hereinafter more fully described and particularly pointed out inthe appended claims. i

In describing the invention in detail reference Will Vbe had to theaccompanying' drawings wherein like characters'ot' reference denotecorresponding parts in the several views, and in whiche- Figure l is aside view of the rear end of a bicycle showing the invention applied;Fig. 2, a rear view of what is shown in Fig.

1 with the spokes and rim of the wheel removed and looking in thedirection. of the arrow in Figi. l, same being on an.enlarged` scalewith respect to Fig. l; Fig. 3, a section on the line 3 3 of .F ig. l onan enlarged Scale; Fig. el, a fragmental perspective view oit' one ofthe alinement rings with its screw mounted therein; Fig. 5, aperspective view of one end of the hub; Fig. (i, a perspective view ofthe sprocket wheel employed inthe mounting; and Fig. 7, a perspectiveview of the brake drum employed in the mounting.

Referring to the drawings i indicates the rear portion of the frame ci?a bicycle: This frame is provided at its extreme rear end with the usualspaced forks B each of which includes arms l0 and. ll connected at theirinner ends by a` har l2. vSlidabl)f mounted between each 'pair oi armsl0 4end'll is an alineinent ring 13 having threaded in the forward endthereof a stud l-L which passes through an opening in the adjacent barl2 and has threaded thereon nuts disposed on opposite sides of the barl2 respectively and whereby the stud may be adj usted longitudinally toeili'ect a desired adjustment of the associated alinenient ring 1?).Each of the alinement rings 13 .is provided with a transverse. passage16 having an enlarged flared outer portion l? .in which is disposed abearing race l Frten'ling tlirougli the passages l5 ot rif-speen x ementrings l?) is a'bolt. i9 having a lined head 2O onY one end and a nutQlthreaded on the opposite end. -Rotatably mounted in oni, of the,alinenient rings 13, is a .hub extension 22 ofi 'a brake drum 23, saidextension passing through the passage 1G of the alinement ring andhaving threaded thereon a retaining nut 25 adapted to erert a thrustagainstv the bearing 1ace 1S, said race in this instance being shown ascarrying roller bearings 26 upon which the extension 22 rotates. Theinner ciad oit the hub of the brake drum is. provided with an extension27 running transversely of the hub and having ono end dish with theperiphery of the hub and its other end spaced from said periphery. @ne

edge of the extension 2,7 is provided with a recess l28 fora purposethatwill presently appear. A v

Rotatably mounted in the other alinement ring 'liis a hub extension 29of a sprocket wheel 30, said extension passing through the passage 1b4of the alinement ring and having threaded thereon a retainingnut 31adapted to exert a'thrust against the bearing race 18. The inner end ofthe hub of the sprocket wheel 23.0 is providedL with ain extension 32'running transversely of the hub andhaving one end Hush with theperiphery ot' the hub and its other end spaced from' said periphery.

One edge of the extension 32 is provided with a recess '53 for a purpbsethat will presently appear. It will be noted that the vextension issimilar in every .respect to the extension 27 on the hub of the brakedrum.

The in'iproved mounting further 'embodies a hub 34 encircling the bolt19 and disposed between the brake drum 23 and the sprocket wheel $30.Each end yof the hub 34 is provided with a recess in Which tl1eextensions 27 and are detachably engaged by movement of the hub in theplane of the frame A. Then the extensions 27 and 32 are seated inrespective recesses 35, screws 36 carried by the hub 34 are operated soas to engage respectively in the recesses 28 and 33 whereby saidextensions are locked Iagainst disengagement from the recesses.

The hub 34 is'provided with circumscribing spoke securing flanges 37 and38 wherebyv the complete wheel may be built up thereon` in the-usual andwell known manner.

In order to remove the hub itis only necessary to withdraw the screws 36from the recesses 28 andy 33 and .then remove the nut 2l and withdrawthe bolt 19. The rim of Ithe wheel associated with the hub 34 is thengrasped and the wheel pulled in the plane of the frame Ap so as todiscngage the extensions 27 and 32 from the recesses 35 when the removalof the wheel is completed. By reversing the operation just described itwill be obvious that the wheel can be reapplied During the operationsjust described it will be apparent that the aline ment rings, sprocketwheel Iand brake drum are not disturbed.

Copies of this patent may be obtained for V from Arelatively to theelements.v

While one form of carrying the invention into practice has beenillustrated and described it will be apparent that various .changes indetails and arrangements can be y resorted to without departing fromthescope of the invention as set forth in the appended claims .and theinvention is therefore in no Way limited to the specific constructionillustrated and described.

` Vhat is claimed is of a "support, a pair of spaced bearings mounted onthe support, an element rotatably mounted in each bearing, and a hubbetweensaid elements detachably interlocking therewith.

241m a wheel mounting, the combination of a support, a pair ofspacedbearings 1. In a wheel mounting, the combination mounted on the support,an element rotatably mounted in each bearing, and a hub betweensaidelements detachably interlocking therewith and adapted to be disengagedthe elements by bodily movement in a plane at right angles to its axisof rotation.

3.' In a wheel mounting, the combination of a. support, a pair of spacedbearings mounted on the support, an element rotatably mounted in eachbearing, a hub having its end portions slidably. interlocked withrespective end portions of the elements and adapted to be disengagedfrom the elements by bodily movement in a plane at right angles toitsaxis of rotation, and means for locking the hub against bodily movement4. In a wheelmounting, of a support, a pair of spaced bearings mountedon the support, an' element rotatably mounted in each bearing,projections on the adjacent ends of said elements and a hub having itsend portions provided with transverse recesses respectively, saidyrecesses opening through one side of the hub and adapted to receive theprojections on the elements respectively to detachably interlock thehub" and elements together.

In testimony whereof, -I afiix my signature,v in the presence of twowitnesses; DURBIN VAN LAW..
